Sulfur dioxide composite salt spray test chamber spray system introduction

Sulfur dioxide composite salt spray test chamber is an environmental test that mainly uses the artificial simulated salt spray environmental conditions created by salt spray test equipment to assess the corrosion resistance of products or metal materials. Sulfur dioxide composite salt spray test chamber is divided into two categories: natural environment exposure test and artificial accelerated simulation of salt spray environment test.

Sulfur dioxide composite salt spray test chamber spray system of 9 features.

1, pneumatic spraying method, air pressure adjustment for the two-stage regulating type: one for the inlet pressure, generally adjusted to 0.3 - 0.4mPa; two for the spraying pressure, in order to meet the latest standards in the spraying pressure requirements, the equipment spraying pressure gauge selected custom high-precision pressure gauge.

2, the spraying method is the use of tower sprayer located in the middle of the studio.

3, the brine before spraying is injected into the spray box through the brine storage tank barrel.

4, the use of non-crystalline nozzle, by atomization, the fog diffusion uniform and free settlement in the test chamber, the height of the sprayer can be adjusted, oriented salt spray, fine fog particles, natural settlement.

5, special quartz glass nozzle, no salt crystallization.

6, spray gas first through the oil and water separator to be oil and water filtering pressure regulation, after the solenoid valve and regulator into the saturator for preheating wetting, then reach the nozzle.

7, the brine tank is built-in hidden and large storage capacity, with drainage valve for easy cleaning.

8, brine atomization before filtering through the filter, to avoid clogging the nozzle debris.

9、Two standard fog collection funnels are placed in the test chamber, which are connected to the measuring cylinder outside the chamber through pipes, so as to monitor the settling amount at any time.

 

Compared with the natural environment, sulfur dioxide composite salt spray test chamber natural exposure to the environment of a product sample to be tested, to be its corrosion may take 1 year, while the test in the artificial simulation of salt spray environmental conditions, as long as 24 hours, you can get similar results.
